Clipper Cargo in Hong Kong- Pan American freight

Pan Am Cargo or Clipper Cargo was a subsidiary cargo airline of Pan American World Airways. Initially Pan Am Cargo used propeller aircraft such as the Douglas DC-4. In 1963, Pan Am’s all cargo jet service began with Boeing’s 707-321C.

Pan Am stopped Pan Am Cargo operations in 1983.(1) I wonder when Clipper Cargo stopped using Hong Kong as a base and if anyone can provide an image or two of their planes at Kai Tak or further information about the outfit here.
